itk copy a image

template<class TInputImage>
class itk::ImageDuplicator< TInputImage >

A helper class which creates an image which is perfect copy of the input image.

This class is NOT a filter. Although it has an API similar to a filter, this class is not intended to be used in a pipeline. Instead, the typical use will be like it is illustrated in the following code:

medianFilter->Update();

ImageType::Pointer image = medianFilter->GetOutput();

typedefitk::ImageDuplicator< ImageType > DuplicatorType;

DuplicatorType::Pointer duplicator = DuplicatorType::New();

duplicator->SetInputImage(image);

duplicator->Update();

ImageType::Pointer clonedImage = duplicator->GetModifiableOutput();

Note that the Update() method must be called explicitly in the filter that provides the input to the ImageDuplicator object. This is needed because the ImageDuplicator is not a pipeline filter.
